to lubricators for feeding a mixture of oil This invention relates moreparticularly and powdered graphiteto engine cylinders, pistons andvalves and other bearings, and

its main objectsare to p'reventprecipitation, orsettling of the graphiteand to maintain aneven mixture thereof with the oil in the reservoirsfrom which the lubricant is supplied to the hearings; to reduce thequantity of oil required for adequate lubrication and generallytoincrease the efficiency and mprove the construction and operation :of

' lubricators of thisclass.

- connectlon wlth engine cylinders, pistons and valves, it is Itconsists in the construction, arrange ment and combinationof parts ashereinafter particularly described and pointed out in the claims.

In the accompanying characters designate similar parts in both figures.

Figure 1 of lubricator to which the invention is applicable and inwhichitis embodied; and Fig. 2 is a similar view of another kind oflubricator embodying the invention.

. Although the invention is illustrated in air spray lubricatorsspecially designed for the lubrication of applicable to other kinds oflubricators for various purposes.

Referring to Fig. 1, whichshows the invention as embodied in alubricator in which provision is made for compressing air to spray thelubricant as it is discharged therefrom, 1 designates the lubricantreservoir having a detachable top plate 2, which is formed with afilling opening and provided with a removable cover 8, for the;opening,"

and a strainer 4:.

A cam shaft 5, passing horizontally through .the reservoir, is providedinside thereof with a number of cams 6, accord ing to the size of the.lubricator,and'at one end outside of the reservoir, with the usualmeans (not shown) of rotation.

The pistons orplungers are connected in correspondlng pairs withyokesll, fitting The pumpv cylinders -7, which are ,sup

portedand guided by one or more hangers gor brackets 12, attached withthe co npressor cyl1nders'8,to the topplate 2, are

adjustable axially toward and from the cam shaft, to ffvary theeffective strokes of the pl-ungers 91. and the quantity of lubricantforcedv thereby from the barrels 7. The bar? rels 7 are adjusted bymeans .oflscrew rods 13, swiveled at their lower'ends in plates 14,

which are'attached to the lower ends of'the barrels and threaded adjacent'to theirlower ends in thehangers or brackets 12. These rods extendupwardly parallel with the I plungers 9. and 10 through the top' plate2, I and are provided at their upper exposed ends with means such asknurled heads 15,

The barrels 7 are formed in opposite sides with inlet and outlet ports16 and 17 and the plungers 9 are cut away or recessed for r a portionof'their length from their lower ends next" to the outlet port 17, topermit the lubricant to 'be ejected through said ports after'the inletports 16 are closed by the plungers intheir downward movement. Theoutlet ports 17 open into'passages 18, which are provided with upwardlyopening spring seated check valves 19, and are connected by tubes 20surrounding the rods 13,

The pipe 30, which leads into the lower part ofthereservoir 1, for agitating the lubricant contained therein, connectsWith the valve chamber below the valve 31. A plunger 35, guided andprovided with packing in the lower end of the valve case,

tension of'its spring for intermittently admitting compressed air intothe pipe 30. A rack 36, guided in a casing or body 37" in I axialalinement with the plunger 35, meshes with a pinion 38 on a rockershaft, which is providedwithan arm 39, for connecting it with an engineor. other machine, and imparting an oscillatory movement to the' pinion.An adjusting screw 40, threaded in the upper end of the rack 36'andfastened in adjusted position by a lock nut 41, affords means forvarying the liftor opening of the valve .31, and hence the quantityofcompressed air admitted to the pipe 30'and the 1 volume and strengthof the air puffs discharged into'the lubricant in the reservoir 1. Thisform of lubricator is providedwith force feed mechanismandconnections(not shown) for taking the mixed lubricant from the reservoir 1 anddelivering itto the cylinder of an engine or tothe bearings of amaQchine with which the lubr cator is conj nected. p

The operation of the compressed air agitator in this form of lubricantis inv effect the i same as that shown in Fig. 1. With the-0s cillationof the pinion 38, the rack 36 is reciprocated, and in its upwardmovement thrusts the plunger 35 upward against the weighted ballvalve31, momentarily lifting it from its seat against the tension of itsspring. A quantity of compressed air determined by the adjustment of thescrew a0, is

thus admitted to the pipe 30, causing a sudden puff of air to bedischarged from its lower end into the lubricant contained in thereservoir 1. As the rack 36 is moved downward-out of engagement with theplunger .35, the plunger is forced by the compressed air back to itsinitial position, and the ball valve 31 isclosed by its spring. Theseoperations being repeated at frequent and regular intervals, thegraphite is kept thoroughly mixed with and evenly distributed throughoutthe ,oil contained in the reservoir 1, from which it is drawn anddelivered as required by the feed mechanism and connection orconnections to the parts or bearing thecover 3 and pouring the oil angraphite through the strainer 4.

In-a lubricator the combination of a lubricant reservolr andmeans for dehvermg a gas such as air inisuccessive pufl'sinto a I fluidlubricant contained in the reservoir.

2. In a lubricator the combination .with a lubricant reservoir'and meansfor feeding lubricant therefrom to a bearing, of means for introducing agas in successive puffs into a-fluld lubricant contalned 1n thereservoir. 3. Ina lubrlcator the 'comblnatlon of a lubricant reservoir,a compressed air conduit leading into sald reservolrbelow the normal]level of the lubricant therein, a

weighted valve normally closing said conduit, and meansforintermittently opening sor having a reciprocating plunger for forcingair throughsaidconduit into lubricant contalned 1n" the reservolr, and aweighted valve in said conduit opening toward the i reservoir.

5. In a lubricator the combination of'a I g lubricant reservoir, acompressed air conduit opening into the lower part of the reservoir, acompressor having a reciprocating plunger for compressin andforcing airin successive puffs into, lu r the reservoir, a weighted valvevin saidconduit opening toward'the reservoir, and a pump connected with thecompressor for supplying a limited quantity oflubricant thereto forlubricating r and sealing its plunger.

6.
